Preparing the Sampler
The 6700SR is shipped to you with the controller mounted on the
refrigerator and a distributor shaft extension installed. Use
Fig-
ure 2 for reference when removing the controller. You must remove
the controller when:
• The internal desiccant needs recharging, the internal battery
needs to be replaced or when the controller needs repair.
• You install a different bottle kit.
Each bottle kit has its own extension so that the distributor arm is
positioned at the right distance above the bottles. You must remove
the controller to replace the extension.
Installing the Distributor Shaft Extension
1. Install the extension before mounting the controller on the
refrigerator.
2. Select the extension of the correct length for the bottle kit,
and screw it on the distributor shaft. Secure it with the set
screw. See Figure 2.
BE SURE THE SET SCREW IS TIGHTENED INTO THE DISTRIBU-
TOR SHAFT’S KEY YOU MAY HAVE TO LOOSEN THE EXTEN-
SION SLIGHTLY AND ADJUST ITS POSITION.
Mounting the Controller

of the case.
2. Fit the mounting rods through the four holes drilled in the
top of the refrigerator.
3. Slip a washer on each rod and secure the controller by tight-
ening the wing nuts.
